Thanks bcdon, lets hope it sounds good!

After intensive research and invaluable comments from Tung and Tig...(thanks guys)!

I decided on an Eminence Delta 12A Speaker for the cab. The thing is, its rated at 400W RMS, 800 peak, which flies in the face of all conventional wisdom.

Specs on the Delta here:

From my googling, this seems to be ideal replacement for the EVM12L. It also seems that this speaker will not color the sound of an amp and has a 'better' sound than the EVM12 L which the speaker enclosure was designed for. Locally, I got one new for about $50 so what the heck, I'll try it. I need to figure out how to "break" in a speaker with a 9 volt battery.

On to the pics!

Internal bracing finished, including port area.




Cleaned up a little and from another angle. You can't see it very well. but the edges have been routed to a rounded edge.
